Rotary Motion Sensor

RMV-BTD—Sensor only
RMPK-BTD—Sensor + Accessory Kit

Specifications and User Guide

Troubleshooting

• Primary Test: Attach the Rotary Motion Sensor to the Vernier data-collection interface and start the data-collection software. Start data collection, then Rotate the axle one revolution counterclockwise. The reading should advance from zero to approximately 6.28 radians.

Note: If you are using a LabPro interface, open the Rotary Motion Angular.cmbl file from the Probes and Sensors folder in Logger Pro.

Additional Troubleshooting

• What is the highest rate of rotation for the Rotary Motion Sensor (standard and Go Direct)?
• With which rotary motion sensors does the Vernier Rotational Motion Accessory Kit (AK-RMV) work?
• Can the PSL (Team Labs) Rotary Motion Probe be used with my Vernier equipment?
• Why does my PSL/Team Labs Rotary Motion sensor not read correctly when using Logger Pro?
• Which Logger Pro experiment file do I use for my rotary motion sensor?
• The rotary motion sensor won't stay zeroed when using LabPro.
• Rotary Motion Sensor will not Auto ID with LabPro.
• Can I use a wired (BTD) Rotary Motion Sensor with TI calculators?
• What are the moments of inertia of the disks included in the Rotary Motion Accessory Kit?
• Can I buy just the adjustable swivel mount from the Rotary Motion Accessory Kit?
• How do I change the rotary motion sensor to read clockwise rotation as positive?
• How do I attach the Swivel Mount to the Rotary Motion Sensor?
• My rotary motion sensor reads zero on LabPro all the time
• What are some experiment ideas I can do with a Rotary Motion sensor?
